MECHANICAL MUSICAL INSTRUMENT= SPECIFICATION forming part of Letters Patent No. 785,394, dated March 21, 1905.

Original application filed July 20, 1904, Serial No- 217,345. Divided and this application filed October 21, 1904. Serial No. 229,367.

7 have invented certain new and useful Improvements in Mechanical Musical Instruments, whereof the following Is a specification, refv erence being had to the accompanying drawings.

My invention comprises subject-matter divided from my application, Serial No. 217,345, filed July 20, 1904:, and relates particularly to instruments provided with automatic playing mechanism, comprisingaseries oflevers in operative relation to sounding devices, such as the strings of a piano, arranged to be actuated in any predetermined sequence by means of independent pneumatic mechanisms controlled by a web of perforated paper which is progressed with respectto a pneumatic trackerbar provided with aseries of apertures corresponding with the series of levers.

It is the object of my invention to provide means to operate the pedals of a piano or similar instrument,particularly the loud pedal, by connecting the same with the pumping mechanism employed to maintain the pneumatic pressure or partial vacuum required for the automatic playing mechanism. Such pumping mechanism usually comprises two pedals independently connected with respective bellows, and, as hereinafter described, I find it convenient to operate the piano-pedal by connection with one of said pumping-pedals independently of the other.

My invention comprises the various novel features of construction and arrangement hereinafter more definitely specified.

In the drawings, Figure I is a perspective view of a portion of the front of a piano provided with automatic playing mechanism within its casing and embodying a convenient form of my invention. Fig. II is a detail view of the member attached to the loud pedal of the piano in Fig. I

The automatic playing mechanism is within the casing I, having the brackets 2, in which the pedal-frame 3 is supported on pivots 4c. The pumping-pedals 6 and 7 are pivotally supported on said frame 3 and are respectively provided with link connections 10 11, extending to the bellows of the automatic playing mechanism within the casing 1. The pedal 14 of the instrument, which is arranged to modify the effect of the playing mechanism, is conveniently provided with the adjustable and reversible member 16, which is detachably engaged therewith by the set-screw 17. The arm 19 of said member 16 is conveniently provided with the roller 20 to encounter the pedal 7 and comprises the slot 22, through which it is connected to the member 16 by the set-screw 23, so that the extent and angular position of said arm 19 may be varied and so that it may be swung into inoperative position when desired. Assuming that said pedal 14: is the loud pedal of a piano, it is to be understood that such a member 16 may be secured on the adjoining soft pedal of the piano in operative relation with the pedal 6.

It is to be understood that I do not desire to limit myself to the precise details of construction and arrangement herein set forth, as various modifications may be made therein without departing from the essential features of my invention.

I claim- 1. In a piano, the combination with automatic playing mechanism, comprising a pumping-pedal; of a member arranged to operatively engage a pedal of the piano; and, means arranged to detachably secure said member to said piano-pedal in operative relation to said pumping-pedal, substantially as set forth.

2. In a piano, the combination with automatic playing mechanism, com prising a pumping-pedal supported by the pianocasing; of an adjustable member supported by the loud pedal of the piano, in operative relation with said pumping-pedal; and, means arranged to detaehably engage said member with said loud pedal, substantially as set forth.

3. In a mechanical musical instrument, the combination with automatic playing mechanism comprising a pumping-pedal; of a member arranged to operatively engage a pedal of said instrument; and, means arranged to detachably secure said member to said instrument-pedal in operative relation to said pumping-pedal, substantially as set forth.

4. In a piano, the combination with automatic playing mechanism comprising a pumping-pedal; of a member arranged to operatively engage a pedal of the piano; means arranged to detachably secure said member to said piano-pedal in operative relation to said pumping-pedal, comprising a set-screw; and, means to adjust said member in operative relation to said pumping-pedal, comprising a set-screw, substantially as set forth.

5. In a piano provided with a pedal, the combination with automatic playing mechanism comprising a pumping-pedal; of means operatively connecting said piano-pedal with said pumping-pedal comprising a member having a set-screw arranged to engage said piano-pedal; an arm having a slotted connection with said member; and, a set-screw arranged to secure said arm and member in adjusted relation, substantially as set forth.

6. In a piano provided with a pedal, the combination with automatic playing mechanism comprising a pumping-pedal; 01 means operatively connecting said piano-pedal with said pumping-pedal, comprising a member having a set-screw arranged to engage said piano-pedal; an arm having a slotted connection with said member; a set-screw arranged to secure said arm and member in adjusted relation; and, a roller at the free end of said arm arranged to encounter the pumping-pedal, substantially as set forth.

In testimony whereof I have hereunto signed my name, at Philadelphia, Pennsylvania, this 20th day of October, 1904.
